Highest temperature in Chongqing on August 4?

Platform comparison

Market context

The real-world event is the **highest temperature recorded at Chongqing Jiangbei International Airport** on 4 August, measured in Celsius and resolved from the Wunderground history page for that station. August is typically Chongqing’s hottest month, with average daytime highs around 34°C and frequent hot days above 40°C, so the market is reading against a genuinely extreme temperature profile rather than an outlier cool-season baseline.[1][16]

The current 0% implied “YES” looks difficult to reconcile with the climatology alone, because multiple sources place Chongqing’s August highs in the mid-30s Celsius and note that 40°C-plus days are common in this period.[1][13][14] Comparable station-based forecasts for Chongqing Jiangbei International Airport also point to highs in the high 30s Celsius in early August, which means the relevant question is not whether it can get hot, but whether the airport station’s observed peak lands inside the market’s specific resolution band.[3][6][12]

For accessibility, the regulatory and compliance context matters more than the weather. Under Germany’s GlüStV framework, prediction markets can face strict restrictions if they are treated as gambling-like products, while in the US the CFTC’s reach can extend to event contracts that resemble derivatives, making venue and user eligibility more than a technical detail. In practical terms, “no-KYC up to $1,500” usually means a user can access the market and transact within that cap without full identity verification, but higher-volume participation may trigger checks that narrow access or delay withdrawals; traders should also watch for any platform-side limits tied to region, verification status, or market category.

Is there a withdrawal cap?
